SEWING-MACHINE.

Specification of Letters Patent.

Patented Nov. 9, 1915.

Application filed February 20, 1906. Serial No. 302,090.

To all whom it may concern:

Be it known that I, HENRY C. MILLER, a citizen of the United States, residing at Waterford, in the county of Saratoga and State of New York, have invented new and useful Improvements in Sewing-Machines, of which the following is a specification.

This invention relates to improvements in sewing machines of the zig-zag stitch forming type, wherein the needle bar is horizontally reciprocated to cause it to operate in diiferent vertical planes, in combination with a compensating device to accurately locate the needle with reference to the looper, to prevent skipping stitches.

Considerable difliculty is experienced in producing uniformity in stitching with high speed machines, due to the fact that the horizontal movement of the needle throws it out of time with the looper. According to my invention I propose to overcome this defect, by the introduction ofmechanism which compensates for the horizontal movement of the needle, so that in any vertical position in its path of travel its eye will always be timed to meet the hook of the looper at the proper time and place.

The invention also relates to improvements in the specific details of construction, all of which will be hereinafter referred to, and particularly pointed out in the claims.

In the drawings: Figure 1 is a side elevation of a conventional buttonhole machine, parts being broken away. Fig. 2 is an enlarged end elevation of the same, parts being in section to more fully disclose the invention. Fig. 3 is a detail elevation of the head of a buttonhole machine, parts in section. Fig. 41 is a similar view looking from the opposite side of the machine. Fig. 5 is a view similar to Fig. 4, but showing the needle bar in its extreme left hand movement. Fig. 6 is a detail perspective view of the compensating mechanism. Fig. 7 is a detail section on the line 50-00, Fig. 1. Fig. 8 is a diagrammatic view illustrating the movement of the needle and the looper. Fig. 9 is a detail view of a different form of my invention. Fig. 10 is a detail of a further modification.

1, indicates a buttonhole sewing machine, of the type shown and described in my Patent No. 1,033,721, dated July 23,1912. However, I desire it distinctly understood that my present invention is not limited to buttonhole machines.

2, indicates a power shaft, carrying a gear 3, which meshes with a gear 41, on a shaft, carrying a nest of cams 5,- opposite said cams is an arm 6, connected by a link 7, with a gate 8, mounted in the head 9. A gear 10, on a. vertical shaft 11, meshes with gear 3, to communicate motion to the lower stitch forming mechanism. On the lower end of the shaft 11., is a gear 14, which meshes with a smaller gear 15, on shaft 16. This shaft is mounted at one end in a bearing 1.7, while its opposite end is supported in a sleeve 18, in a bearing 19. On the end of shaft16, is a beveled gear 20, meshing with a beveled gear 21, on a looper shaft 22, having a bearing in a swinging support 23, from which sleeve 18, extends. On the end of the sleeve is fastened a collar 24:, provided with notches 25 and 26, with which a latch 27, cooperates to lock the looper in position. The looper 28, having the usual hook 29, is mounted to revolve with shaft 22, and it also carries a bobbin 30. These parts are of well known construction and need no further detail description.

The upper stitch forming mechanism is controlled by my improved compensating mechanism which I will now proceed to describe' The gate 8, is mounted on a rod 35, which is in line with the center of rotation of the looper, and is fitted in a bearing 36 and thimble 39. The lower end of rod 35, is secured in bearing 36 by a set screw 38, while its upper end fits in threaded thimble 39, screwed into an opening 37, in head 9. By releasing set screw 38, rod 35, may be re moved, which will also permit removal of the gate 8, for repairs, etc., the lower end of thimble 39, bears on the bearing 8 of gate 8, and byadiusting said thimble, and locking it by a lock nut 10, lengthwise wear of the gate may be taken up.

Mounted to slide on rod 35, is a sleeve 41, having a lug 16, and a cam groove 47. Lug 46, fits in a guide way 48, on the inside of head 9, to maintain the sleeve in a determinate vertical path of movement. A connecting rod 49, has pivotal connection with the lug 4:6, and its opposite end is connected to a disk mounted on the power shaft, whereby reciprocal movement is imparted to the sleeve. Cam groove 4&7, extends from a point .50 toward the left and is equal in length to A needle bar -11, is carried by the gate,

and in its lower end is a needle 52, secured 1n place by a set screw 53, the downward throw of said bar being limited by a stop 1-1 on the upper end. Adjustably mounted on the needle bar 41, as by a set screw 54, is a sleeve 55, provided with a lug 56, and a fork 57; lug 56, engages cam groove 47, while the fork 57, embraces the sleeve 41, to provide a bearing for sleeve 55 when the needle bar is operated. Because of the location of the fork 57, it keeps the eye of the needle presented to the hook 29 in the same relative position irrespective of the vertical plane of movement of the needle bar, and also retains lug 56 in proper position in groove 47.

In operation, the nest of cams, through the described connections horizontally vibrate the needle bar and gate, while the disk reciprocates sleeve 41, and through the cam groove 47, and lug .56, vertical movement is imparted to the needle bar. Assume the needle bar to be located at its extreme right hand movement, and also its downward limit of vertical movement as shown in Fig. 4; cam groove 17, caused the lug 56, to travel to the point 50, which necessarily raised the needle bar to time the eve with the hook 29, to take the loop 52. The movement of the lug 56 to point 50, of the groove will cause the movement of the needle to be simulta neous with the movement of the sleeve 41. Now assume the needle bar to be atits extreme left hand position, and the sleeve 41, started on its up stroke as shown in Fig. 5. In this position, the widest portion of the cam groove occurs, and while the sleeve 41,

has driven needle bar down just as far as when operating at the point 50, said needle bar dwells and is not therefore simultaneously raised with sleeve 41, (as in the previous position) giving the hook an opportunity to catch up to the needle eye. By'the time hook 29. takes the loop the lower inclined edge 4-7", of the cam groove picks up the projection 56, and raises the needle bar, the loop having been taken by the hook at the same determinate point as when taken when the gate was thrown to the limit of its extreme right hand movement. This operation is due to the fact that the cam groove is of a greater width at the left of the vertical plane of movement of the needle bar, hence causing the needle bar to be retarded sufficiently until thehook catches up with it. The cam groove'therefore acts I as a compensating means-between the hook skipping of stitches.

and the eye of the needle, thus preventing It is evident if the looper were evolved in the opposite direction'to' the showing in the drawing, the widest portion of the cam would be to the right of the vertical plane of movement of the needle bar, and the narrowest point to the left.

While I have described the two extreme right and left hand positions of the needle, it is of course to be understood that the compensating movement of the parts in any position in the path of travel of the needle bar will be such as that the same determinate point of the needle Will be met by the hook of the looper. But to more particularly emphasize the movement I will briefly describe the action of the parts when moving from the left hand position to the normal or central position. When the sleevel, is raised and the needle is up and out of the fabric the vibrating means moves the gate toward the right and the lug 56, travels in the cam groove until the central vertical plane of movement of the needle bar is reached, so that when the sleeve, after having been driven down to form a stitch, starts on its up stroke it will not pick up the projection 56, until edge 47", reaches it, or in other words the needle bar is retarded just half the time it was when in the left hand position, giving the hook time to catch up to the loop, as previously described.

It will be observed that the sleeve 41, acts as a bearing for the sleeve 55, in both its vertical and horizontal vibrating movements, which insures the needle being rotated on the same center as the looper. By arranging the compensating means as de scribed, the same determinate point of the needle will always be met by the hook of the looper under precisely the same conditions and exactly the same horizontal alinement, as I provide for compensating for the horizontal vibrations of the needle, as well as means .for compensating for the vertical reciprocations of the needle with relation to the looper.

The gate is provided with a slot 60, through which the threaded end of link 7, passes. On each side of the gate, and working onthe threaded end of the link are two lock nuts .61 and 62, for connecting the link to the gate. The purpose of this construction .is to permit the operator to alterthe throw'of the needle, should occasion require.

When it is necessary to remove the bobbin,

looper, without destroying the mesh of gears 20 and 21, and the time of meeting of the hook and needle.

In Fig. 9, the walls of the cam groove are inclined but parallel. This construction operates satisfactorily with a certain type of machines, in substantially the same manner as before described, except the time of movement of the projection is changed.

The structure shown in Fig. 10, is for use when the stitches are not unusually long, as for instance in a plain buttonhole. In this construction there is no compensating cam. The fork of arm 57, engages the flanges of the groove l-l and serve as a means for transferring the vertically reciprocating movement of sleeve L1, to the needle bar, the latter as in the preferred form of the invention swings on the same axis as the gate.
